The ride held the title of longest roller coaster in the world from 1991 to 2000.
Europe’s longest roller coaster, the Ultimate at Lightwater Valley in the UK, will soon be dismantled, according to a post on the ride’s website.
“The ride has been out of service for some years now and the process of assessing the viability of bringing it back into use was a long one.”

Now, an artificial pancreas also called a closed-loop system, may provide relief for people with type 1 diabetes, according to a post on BMJ published on Tuesday.
The company captures and transforms excessive CO2 emissions into rocks, and buries it underground.
The world’s first company to successfully absorb carbon dioxide from the atmosphere and permanently store it underground for a paying customer has announced success.
“Providing our first corporate customers with CDR services is an exciting milestone we’re proud to reach with the rigorous validation of a certifying 3rd party,” said Christoph Gebald, co-CEO/founder of Climeworks.

Making predictions is never easy, but it is agreed that cryptography will be altered by the advent of quantum computers.
Thirteen, 53, and 433. That’s the size of quantum computers.

In fact, the problems used for cryptography are so complex for our present algorithms and computers that the information exchange remains secure for any practical purposes – solving the problem and then hacking the protocol would take a ridiculous number of years. The most paradigmatic example of this approach is the RSA protocol (for its inventors Ron Rivest, Adi Shamir, and Leonard Adleman), which today secures our information transmissions.
This process can occur endlessly and allows the jellyfish to escape death.
Achieving immortality has driven human beings throughout much of their history. Many peculiar legends and fables have been told about the search for the elixirs of life. Medieval alchemists worked tirelessly to find the formula for the philosopher’s stone, which granted rejuvenating powers. Another well-known story is the travels of Juan Ponce de León, who searched for the mysterious fountain of youth while conquering the New World.
But to this day, no one has discovered the keys to eternal life. However, there is one exception — a creature no more than four millimeters in size, Turritopsis dohrnii.

State-of-the-art methods of information security are likely to be compromised by emerging technologies such as quantum computers. One of the reasons they are vulnerable is that both encrypted messages and the keys to decrypt them must be sent from sender to receiver.
A new method—called COSMOCAT—is proposed and demonstrated, which removes the need to send a decryption key since cosmic rays transport it for us, meaning that even if messages are intercepted, they could not be read using any theorized approach. COSMOCAT could be useful in localized various bandwidth applications, as there are limitations to the effective distance between sender and receiver.
In the field of information communication technology, there is a perpetual arms race to find ever more secure ways to transfer data, and ever more sophisticated ways to break them. Even the first modern computers were essentially code-breaking machines used by the U.S. and European Allies during World War II. And this race is about to enter a new regime with the advent of quantum computers, capable of breaking current forms of security with ease. Even security methods which use quantum computers themselves might be susceptible to other quantum attacks.
The first launch of SpaceX’s massive rocket, called Starship, could be coming soon. The company shared a series of photos highlighting the vehicle’s progress ahead of its highly anticipated test flight.
Starship consists of two major components: a massive first-stage booster called the “Super Heavy” and an upper stage known as “Starship.” In typical SpaceX fashion, both aspects of the craft are designed to be fully reusable.
If anyone accuses you of “living in a bubble” there is an astronomically correct, if not always convincing, response: we all do. The Sun sits inside what is known as the Local Bubble, a space within the Milky Way galaxy some 1,000 light-years across in which interstellar material is scarce. It can be hard to map something from the inside, but that’s what astronomers have tried to do with the Local Bubble’s magnetic fields.
It’s easy to imagine that anything distinctive about our Solar System’s location must be connected to our apparent uniqueness. However, superbubbles like our own are not particularly rare; indeed, the galaxy has enough of them to prompt comparisons with Swiss cheese. They are left behind by supernova explosions that push gas and dust out of surrounding regions. The material swept out by the explosion concentrates on the bubble’s surface – still so thin it would be considered a vacuum by Earthly standards, but dense enough to trigger star formation.
Nevertheless, our knowledge of superbubbles in general and the Local Bubble, in particular, is almost as thin as the material inside. The magnetic mapping of the Local Bubble, presented at the American Astronomical Society’s 241st meeting, is an attempt to address that.
Each of these piles represents a critical mineral needed to make the transition from fossil fuel-based energy to renewables possible.
Guest contributor, Jane Marsh, describes the challenges the U.S. and its allies face in securing minerals used for the energy transition.

Replacing fossil fuel with hydrogen seems like an ideal solution to make transportation environmentally friendly and to provide a backup for intermittent energy sources like solar and wind. But how environmentally friendly is hydrogen really? And how sustainable is it, given that hydrogen fuel cells rely on supply of rare metals like platinum and iridium? In this video, we have collected all the relevant numbers for you.
